Element array circuit and sensor

An element array circuit comprising:

• one or more first wirings that include respective one or more first ends and respective one or more second ends;
• a plurality of second wirings, the second wirings each extending in a direction different from a direction in which the one or more first wirings each extend;
• a plurality of impedance elements, the impedance elements each being coupled to both one of the one or more first wirings and one of the second wirings;
• one or more operational amplifiers each including a positive input terminal to be set to a first potential, and a negative input terminal couplable to one of the second wirings;
• one or more first selectors each coupled to corresponding one of the one or more first ends and configured to select one option from a first option group, the first option group including a first option to apply the first potential to the corresponding one of the one or more first ends and a second option to apply a second potential different from the first potential to the corresponding one of the one or more first ends;
• and
• one or more second selectors each coupled to corresponding one of the one or more second ends and configured to select one option from a second option group, the second option group including a third option to apply the first potential to the corresponding one of the one or more second ends and a fourth option to apply the second potential to the corresponding one of the one or more second ends.
